Marine Mammal Protection Act

Lilly s studies of the human brain sparked his interest in the brains of other intelligent mammals, dolphins in particular. Lilly performed two long stretches of experiments in dolphin intelligence and human-dolphin communication, one series in the 60s and a second in the early 80s. These efforts bore fruit in ideas that were published in several books, notably Man and Dolphin, and that many believe to have influenced favorably the passage of the landmark Marine Mammal Protection Act. 

Kempthorne was referring to the Marine Mammal Protection Act, which in every way that matters for the polar bear is far weaker than the Endangered Species Act, particularly because only the latter allows for the protection of critical habitat.
